What is does a metronome look like?

A metronome typically resembles a small, triangular or rectangular device with a pendulum or digital display. Traditional mechanical metronomes have a swinging arm that ticks to indicate tempo, often enclosed in a wooden or plastic case. Digital metronomes may have buttons for setting beats per minute (BPM) and often feature a screen for visual feedback. They can also come in various forms, including clip-on versions for musicians.
